Newton’s Three Laws of Motion By Yarelis Barrera Isaac Newton • Isaac Newton was born on January 4, 1643 in a hamlet in Lincolnshire, England • He passed away March 31, 1727, he lived to be 84 years- old. • Formulated gravitational theory in 16651666 after watching an apple fall out of a tree. Galileo • Galileo was born in 1564 and died in 1642 • Galileo proved the Copernican hypothesis • He made us understand how objects moved on the surface of Earth and of gravity. First Law of Motion • Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it. • First law of motion is when an object is moving and there’s something that makes it stop. Second Law of Motion • The relationship between an object's mass m, its acceleration a, and the applied force F is F = ma. Acceleration and force are vectors (as indicated by their symbols being displayed in slant bold font); in this law the direction of the force vector is the same as the direction of the acceleration vector. • Second law of motion is when velocity of an object changes when it is subjected to an external force Third Law of Motion • For every action there is an equal and opposite reaction. • Third law of motion is when there is always an equal and opposite reaction for every action in nature
